IPC: F02N15/02
Filed: 1918-07-18
Abstract: 129,463. Reynolds, C. H. July 18, 1918. Turning-gear.-In an electric starter in which a dynamo-electric machine can be operated as a motor to turn the engine through an epicyclic gear, or as an engine-driven generator, a clutch between the armature and the engine crankshaft is controlled by a lever which also controls a holding pawl for a member of the epicyclic gear. The pawl is removed to free the gear before the clutch is brought into engagement, thus avoiding the risk of damage in the event of backward rotation of the engine. In the form shown, the epicyclic gear comprises a sun-wheel a fixed on the armature shaft b, planet-wheels d on a carrier g secured to a pulley j or a sprocket or gear wheel in driving-connexion with a clutch member on the engine shaft, and an internally-toothed wheel i. When the machine is driven as a generator, pawls r on the spindles e of the planet-wheels engage internal teeth on the wheel i, and the gearing rotates as a whole. When the machine operates as a motor, external ratchet teeth on the wheel i are engaged by a pawl actuated by the core of a solenoid s in circuit with the motor. A pedal which switches on the current to the motor and the solenoid effects at the same time the release of the clutch on the engine shaft ; when the motor has been set in rotation, the pedal is released, cutting off the current, allowing the pawl to reengage the gear wheel i, and closing the clutch. The clutch is preferably employed to couple the two parts of an engine fly-wheel as described in Specification 123,342, the free portion of the flywheel being first set in rotation by the motor and then clutched to the fixed portion at the same time as the wheel i is released from its pawl.

Filed: 1924-05-19
Abstract: 222,058. Brown & Sons (Huddersfield), Ltd., D., Sykes, A., and Kitchen, H. E. May 19, 1924. Milling.-In a cutter-feed mechanism for a gear-cutting machine the cutter head is fed intermittently by means of eccentrics which reach their dead centre when the full depth of cut is attained so that the cutter is fed by gradually decreasing steps and approximately the same amount of metal is removed at each cut. The cutter head 1 is mounted on a slide 2 adjustable on the bed 3 and is provided with members 31 having eccentric pins 32 and carried on vertical shafts 30 operated through worm-wheels 29. The eccentric pins are fitted into blocks 33 working in transverse slots in the slide 2. The worm wheels 29 are operated from worms 28 on a shaft 27 driven through change gears 25 from a. shaft 19 driven intermittently by a ratchet wheel 24 operated by a pawl 20 actuated by an eccentric 23. The pawl 20 is normally held inoperative by means of a projection 18<2> on a member 18 loose on the shaft 19, but is rendered operative by means of a block 17 on a lever 16 which intermittently operates the member 18 to remove the projection 18<2> from the pawl. The ratchet wheel is then rotated to apply the feed until the pawl is again disengaged by the projection 18<2> whereupon the feed stops until the next actuation of the lever 16. The latter is operated through its shaft 13 and a lever 14 which is rocked periodically by means of dogs 11 spaced around a wheel 9 driven from an eccentric-operated ratchet 6. The number of dogs 11 is equal to the number of revolutions of the blank required to complete the teeth. In order to stop the feed automatically when the full depth of cut is reached and the eccentrics reach their dead centre position, the worm wheel 29 is provided with a slot in its upper surface and, at the correct instant, a spring-pressed member 35 drops into this slot and the part 35<2> engages a runner 37 on the pawl 20 to hold the latter inoperative.

Abstract: 294,308. Spong, J. W. May 10, 1927. Outting and slicing vegetables.-A cone-shaped casing 8 having a plate 9 closing its narrow end is supported on a pedestal 1 by a hollow shaft 10 extending from the plate 9 into a bearing 4 formed at the upper end of the pedestal. A screw clamp 3 secures the pedestal to a table. The upper roll of the casing is provided with an opening having lips 12 that serve as guides for receiving a hopper 13. A hollow shaft 15 fitting in the shaft 10 is screw-threaded and internally flanged at one end, and at the other carries a plate 14 to which two 'diametrically-opposite curved walls 18, 19, are secured, one edge of each wall carrying a knife 20, 21, whilst to the other edge of each wall a conically curved spring steel plate 22, 23, is fixed. The distance of the plates 22, 23, from the knife-edges 20, 21, and so the thickness of the slices cut, is adjusted by pressing strips 25 carried by a central shaft 24 adapted to be drawn into the shaft 15 by a wing nut on a screw thread 24<a> at the end of the shaft 24. A spring 26 hearing against the internal flange of the shaft 15 tends to move the strips 25 away from the plates 22, 23. For slicing oranges or potatoes an ordinary hopper 13 is used, arranged at the top of the casing, but for slicing runner beans and similar long articles the hopper 13 is withdrawn and a plate 31 substituted, this plate carrying guides 32 to direct the beans to the knives. The casing 8, when the plate 31 is used, is rotated through approximately a right angle in its supporting bearing 4, the plate 9 carrying a screw clamp 29 riding in a slot 7 in a plate 5 at the end of the bearing 4 to facilitate such adjustment.
